Review on 🧼 Zud Heavy Duty Cleanser, 16-Ounce (Pack of 6): Powerful Cleaning Solution for Tough Stains and Grime by Paul Stephenson

Never heard of it, but tried it. I attempted to restore a 1940's porcelain sink to its former glory. I was impressed. He did the painting with no problems. Rust and scratches are not a problem. I had to get into the cracks with a toothbrush. I sealed it and it looks beautiful. Much better than a comet. Sometimes it smells like rotten eggs (sulfur?), but the smell isn't strong. Mostly imperceptible. There is no smell after rinsing. I was prepared that it would be very toxic or smelly, but it seems quite soft to the touch. After a while I threw away the gloves.
